European automakers overstate fuel economy by 40% on NEDC cycle

Volkswagen is apparently not alone among European automakers when it comes to giving out funny emissions or fuel economy numbers. It turns out that pretty much everyone across the Pond is doing it. So much, in fact, that, on average, the difference between European vehicles' fuel-economy and emissions figures and real-world driving results is about 40 percent, Bloomberg says, citing a report from Brussels-based Transport & Environment. Yes, 40 percent. Mercedes-Benz was the worst offender, as the Daimler division on average overstated its vehicles' fuel economy by 48 percent, said the study, which used data from International Council on Clean Transportation (ICCT). That automaker isn't exactly a world-beater for fuel economy in the US. In fact, two of its models, the Mercedes-Benz G 63 AMG and the G550 (pictured), showed up on the American Council for an Energy-Efficient Economy's (ACEEE) annual list of cars that are "meanest" to the environment. "The information provided by manufacturers on fuel consumption is based on the NEDC test cycle, which is prescribed by law and conducted in a laboratory. Since real driving conditions generally deviate from conditions in the laboratory, the consumption figures can also deviate from the standardized figures. Since T&E has unfortunately not published the test conditions used in its study, it is not possible to provide a useful analysis of the test results," Mercedes-Benz wrote in an e-mailed statement to Autoblog. "The data pool used also does not allow a thorough scientific assessment. Mercedes-Benz emphatically supports the introduction of the WLTP (Worldwide Harmonized Light Vehicles Test Procedure). This is supposed to replace the NEDC with the aim of bringing the rated fuel consumption and the actual consumption closer together. We also actively support the dialog between industry (ACEA) and the authorities, and are in regular contact with the EPA and the ARB in the US." The ICCT is the group that helped spur the investigation that led to the Volkswagen diesel-emissions scandal we're all still talking about, so it shouldn't expect Christmas cards from the largest German automakers this year. This new study came from data taken from about 600,000 cars. That's a lot of funky air floating over Rome. The overstatements were pretty widespread, too. The fuel-economy of the BMW 5 Series was overstated by almost 50 percent, as was the Peugeot 308's.

2015 Mercedes-AMG G65 Review

A German friend who lives in Munich told me she might have to retrieve her car from Innsbruck, Austria while I was in Germany to visit her. I said I'd be happy to chauffeur her to the Tyrol in a Mercedes-AMG G65. She responded to the offer with this question: "You mean – in the G65 Rap Train?" I had no idea what it meant, but the name stuck. Her reasoning was that I would be taken for an American rapper, because what other black American would be cruising south, East, and west Germany for ten days in a 272,000-euro, 5,676-pound chunk of... well, let's just say it: bling. Mercedes created the G65 by installing its 604 horsepower, 6.0-liter, twin-turbo V12 in the G-Class engine bay, and laying oodles of quilted leather inside the cabin. Introduced to markets outside the US in 2012, it sat above the twin-turbo, V8-powered G63 that remained the top-of-the-line here. After years of denial, US buyers will finally get their chance to buy the G65 in November for $217,900. It's a 272,000-euro, 5,676-pound chunk of... well, let's just say it: bling. A grandiose, body-on-frame SUV with a price as momentous as its horsepower might appear silly, but Mercedes can point to plenty of good reasons to bring it here now. In the abstract there's customer demand, AMG boss Tobias Moers having said, "There are AMG fans for whom our V12 biturbo engine is the measure of all things." Concrete justification is in the sales numbers: in May 2010 the G-Class sold 99 units in the US on its way to 919 units for the year. In May 2015 US buyers took home 302 G-Classes, and only five months into this year the brand has sold 1,448 of its ultimate off-roader. The G63 outsold the less expensive G550 in the US in both 2013 and 2014. In 2013 the G63 was the best-selling AMG product in the US, and the G lineup posted its best-ever sales year globally during what was its 35th year on the market. Competitive reasons are likewise substantial. The Bentley Bentayga, Range Rover Sport SVR, Lamborghini Urus, and a Rolls-Royce "that can cross any terrain" will soon join the retail celebration of six-figure SUVs. By getting the G65 here first, Mercedes gets the head start. The burble dripping from the quad pipes is quieter on G65 than the G63. In spite of its price, the Rap Train isn't ostentatious – the sample I was given to drive wearing a beautiful coat of muted satin gray. Because Mercedes is going for a more elegant look for the top of the line G-Wagen, the US-market G65 comes without bull bars.

Recharge Wrap-Up: No new Smart Roadster, Africa to UK on one tank, Duke's efficient axial engine [w/videos]

Smart will not make another generation of the Roadster, but a Smart SUV might be in the cards. According to Smart's CEO, Annette Winkler, "The Roadster isn't a profitable business case. Everybody is keen on the car, but nobody wants to pay the bill." What Car? states that Smart is likely planning a baby SUV to take on the Nissan Juke and its ilk. But for the immediate future, Winkler says Smart "must focus on how we can maximize potential of the Fortwo and Forfour. That is strategy number one." Read more over at What Car?. A Mercedes-Benz E300 Bluetec Hybrid made the 1,223-mile trek from Africa to the UK on just one tank of fuel. Driven by Andrew Frankel of Autocar, the diesel hybrid left Tangier, Morocco with a full tank of gas (using the optional 80-liter fuel tank), and arrived in Goodwood with the car indicating 100 miles of range left. Frankel and his co-driver averaged 61.2 miles per gallon (73.6 mpg UK) on the intercontinental journey through four countries, despite elevation changes and a traffic jam. See the first video below for more information, or check out the article at Carscoops. Duke Engines promises simplicity and efficiency from the axial engine it's developing. Rather than lining up the cylinders, this engine arranges them in a circle, which allows Duke to avoid unnecessary weight. The five-cylinder, four-stroke motor manages the same amount of powerstrokes per revolution as a standard six-cylinder mill, but weighs 30 percent less. It also has much fewer parts, says Duke. Its high compression ratios mean more power with less fuel, which adds up to more efficiency and fewer emissions. The second of the two videos below, which we first found over at Sploid, explains Duke's axial engine. This content is hosted by a third party. To view it, please update your privacy preferences.
